| dc.description.abstract | Cauliflower planted along the edge of the highway is at risk of exposure to lead (Pb) contamination originating from passing motor vehicle activities. This study aims to analyze the lead (Pb) content and characteristics of cauliflower plants in vegetable gardens in Berastagi Sub District, Karo District. This type of research is descriptive with a quantitative approach in conducting laboratory examinations by applying the Atomic Absorption Spectrophotometry (AAS) method to determine lead levels. The results of the study conducted at 3 sample points showed that the average highest lead levels were at a distance of 100 meters from the highway with a value of 0.1877 mg / kg which does not exceed the maximum limit of heavy metal contamination in processed food of 0.2 mg / kg according to BPOM Regulation No. 5 of 2018, so it still meets the applicable requirements. These lead levels are derived from high levels of motorized vehicle activity and agricultural activities such as the use of fertilizers and pesticides, water sources, volcanic eruptions, and other factors that trigger lead buildup in cauliflower. Characteristics related to the presence of lead include plant age, farmer treatment of leaves, cauliflower production, and distribution. The ADI calculation found that the acceptable daily intake limit is 228 grams per day, meaning cauliflower is still safe for consumption. It is recommended that farmers plant shade trees around their crops to reduce exposure to heavy metals like lead. Consumers should be more careful in selecting vegetables and washing them immediately before cooking to reduce lead levels in cauliflower. The Health Office and the Food and Drug Monitoring Agency (BPOM) should provide education and counseling regarding the dangerous impacts of heavy metal exposure, especially lead (Pb), to farmers and the public. | en_US |
